Among all the large whales on Earth, the most unusual and least studied is the narwhal, the northernmost whale on the planet and the one most threatened by global warming. Narwhals thrive in the fjords and inlets of northern Canada and Greenland. These elusive whales, whose long tusks were the stuff of medieval European myths and Inuit legends, are uniquely adapted to the Arctic ecosystem and are able to dive below thick sheets of ice to depths of up to 1,500 meters in search of their prey-halibut, cod, and squid. Join Todd McLeish as he travels high above the Arctic circle to meet: Teams of scientific researchers studying the narwhal's life cycle and the mysteries of its tusk Inuit storytellers and hunters Animals that share the narwhals' habitat: walruses, polar bears, bowhead and beluga whales, ivory gulls, and two kinds of seals McLeish consults logbooks kept by whalers and explorers and interviews folklorists and historians to tease out the relationship between the real narwhal and the mythical unicorn. In Colorado, he visits climatologists studying changes in the seasonal cycles of the Arctic ice. From a history of the trade in narwhal tusks to descriptions of narwhals' vocalizations as heard through hydrophones, Narwhals reveals the beauty and thrill of the narwhal and its habitat, and the threat it faces from a rapidly changing world. "[The book] is a personal account of the latest scientific findings on narwhals and on ways the Arctic environment is changing. . . . [it] feels like a privilege to see one's favorite study animal portrayed as it has been here in a well-written popular book for a broad audience." --M. P. Heide-Jørgensen "Quarterly Review of Biology" "Anthropology, conservation, biology and local cultural and economic considerations blend effortlessly in this account. Ultimately the reader comes away with a profound awareness of the complications involved in maintaining in perpetuity a long lived species whose behavioral and ecological circumstances ironically leave it vulnerable to anthropogenic perturbations." --Science Book and Film Review "American Association for the Advancement of Science" (1/1/2013 12:00:00 AM) "As one of the first general-interest books for adults dedicated to the narwhal, it's an important first start. Full of science, story, and some amazing images, Narwhals introduces us to the 'sea unicorn's' world." --Elizabeth Bradfield "Orion" "Based on interviews with researchers and his own research, McLeish weaves a compelling story about narwhals and the impact of the changing climate on their survival. . . . This book is a great read for general audiences and students as well as scientists interested in narwhals." -- "Choice" "His expertise shines in this pithy, entertaining book, which concludes with a sober assessment of the future for this species, one of only three truly Arctic cetaceans, in a warming world." --Kieran Mulvaney "BBC Wildlife" "McLeish provides a broad view of the narwhal's history and legend, remaining awestruck and deeply concerned for a species that remains a miraculous creation." --Colleen Mondor "Booklist" "Narwhals is reminiscent of many geographers' first field experiences: journeys of discovery, both about the subject matter and about ourselves. . . . A lighter, more feel-good book about the joy, wonder, and Type II fun of a true research-based adventure." --Russell Fielding "AAG Review of Books" "Part of the book's strength lies in how McLeish captures the vivid sensory world of the Arctic." --Doug Norris "IndependentRI" (1/1/2013 12:00:00 AM) "Todd McLeish goes deep into the narwhal-- from its mythology to its biology." --Beth Daley "The Green Blog" (1/1/2013 12:00:00 AM) Todd McLeish is the author of Golden Wings and Hairy Toes: Encounters with New England's Most Imperiled Wildlife and Basking with Humpbacks: Tracking Threatened Marine Life in New England Waters . He lives in Pascoag, Rhode Island.
